**EDIT** Also, what's the best video editing software to maintain the high frame rate and 4K resolution? At the moment I use Corel Video, it definitely has a 4K option for encoding, but if I use the 1080p mp4 settings, will it keep the high frame rate?
having looked at the Hero for £99 - it looks good but the downside I can see is straight away is "integrated battery" - i.e you can't carry extra ones and change them.
That could be a deal brake for some. Videos popping up on youtube now.
Battery life was the only thing that would have made me replace my 3 so good to know nothing's reallly changed.
